But now to the device, especially compared to the 7390th
The synchronization and line quality with VDSL is definitely better, but which should also be no surprise you but contains the better modem chipset is also found in the 3390 or the 7360 application.
The WLAN performance is both the 2.4 GHz and 5 GHz band a little bit better, I would say, whether it is clearly better with 802.11 AC I can not say for lack of hardware at the moment. The throughput remains at 300 Mbit enabled devices definitely a little longer at a higher level, but this also could simply be due to the 3x3 MIMO.
However, the entire range is unfortunately a little bit worse, because up to the garden, the WLAN is no longer enough.
The antennas but have now been etched directly onto the motherboard with on the layout as would certainly have been more potential for optimization especially as it now no longer exists Hirose U.FL connectors on the board in order to other (external) use antennas , There is only the for something useless test sockets.
In DECT range Although a higher signal strength on the MT-F will be displayed, but it cracks definitely in the same places as before with the 7390, also here was simply wasted potential, even if in the Box 2. DECT antenna now from a 3cm long wire consists of vertical from the board in the room stretched.
The processor of the Box is now a dual core of course a bit more power and brings with it seems that the throughput via VDSL now is a bit faster, measurable which is not however. It fluppt just a little more;)
The USB3.0 throughput with a very good USB stick to a PC around 90MB / s read and 60 MB / s when writing is just s read and 8MB / s write braked at the box 11 MB /, an HD USB3.0 afforded here identical values, good but the box is indeed now times no NAS.
The firmware is definitely not yet ready and hopefully also some potential, at the moment it is very slow compared to 7390 and just slowly. But here there is still hope in the other boxes there was indeed getting better, even if the determined again takes 6-12 months. Maybe you can so also still something to change in the performance.
Conclusion: At the moment of purchase is not worth, at least if one already has a 7390 and no problems occur Sync. What the future brings remains to be seen and banana products indeed have a long tradition at AVM :-)
Therefore, there is of me at the moment only 2 stars for the box.
But I will continue to monitor.
[Update]
On the one hand is at the top in Orange "Amazon Verified Purchase" way, because I have just bought this box of Amazon and the other I change my rating to 3 stars because if you do not come from a 7390, it is in itself only once in order.
However, if you a 7390 has, you should first stick to it, at least as long as one has no problems with the sync, otherwise it is not worthwhile at the moment simply (yet).
Here you could for 289 euros simply expect more.
I will also keep the box and the tires for this award because bananas can and I think that AVM otherwise does a very good job, especially in terms of development of the software!

The USB stick was just like the HD formatted with NTFS, I've now tested again with a FAT32 formatted drive and come to 14.5 MB / s reading and about 12 MB / s when writing.
